Read Battery Level from Shell?

[jesmith]

Is there a /proc interface or some other trick I can use to snag the top battery level from a shell script?

On other boxes, I've used:

cat /proc/acpi/battery/BAT0/state

Anything like that on a TB?

The highest I've seen it go was 4127, but as soon as I unplug the charger it drops to ~3700. The value jumps around by ~0050.

Thanks for the link (the stupid forums won't let me search for "Battery"!).

That directory does seem to be the fount of all battery knowledge. I'll have to play with it to see how things change as it discharges.

latest patch in git suggests, that in the released image it is impossible to read battery level when charger is not connected (the last value is frozen, so you won't see any changes).
it can be done with the patch, so you'd have to compile your own kernel. or wait for the next image.

Waiting for the next image doesn't sound like a problem. Any idea when we'll see it?

[matejcik]

can't tell.
based on the release intervals so far, my guess is half of february
